IMPROVEMENT IN CLEARER-ROLL FRAMES FOR DRAWING AND SPlNNl NG MACHINES.

Specification forming part of Letters Patent no. 201,303; dated Maren12, 1818; application fire-u April 19, 1811'.

To all whom it may concern:

Be it known that we, FRANKLIN TWITCHELL and OHAs. A. RICHARDSON, ofNashua, in the county of Hillsborough and State of New Hampshire, haveinvented a new and useful Improvement in Clearer Roll Frames for Drawingand Spinning Machines, of which the following is a specification: In theaccompanying drawings, Figure 1 represents a front vertical view of theelongating and paying-out part of a common ringspinning frame with ourimprovement attached. Fig. 2 represents a plan of the same with ourimprovement removed. Fig. 3 represents our scavenger-roll. Fig. 4represents a section of Figs. 1 and 2 on line a; also an inside end viewof the bracket G of our improved attachment.

Similar letters of reference indicate corresponding parts.

The object of our invention is to furnish a convenient device forlicking up the bits of flying cotton in the manufacture of thread, soarranged as to be conveniently handled.

The invention consists, mainly, of a roller and a frame which retainsthe roller in its place, in connection with the ordinary frames used inthe manufacture of thread or yarn in a cotton-manufactory, and may beused to great advantage on spinning frames and stretcher-rolls onrailway-heads and drawingframes, in any place where it is desirable togather up the stray bits of cotton.

Referring to the drawing, A represents the frame which supports thevarious mechanism. B B are parts of a frame which hinges to A at y andy, and sustains and keeps in place the rollers G and 0. This frame, withits supported rollers, may be raised from the rollers a and b at will.On this frame are two vertical projections, l and l, on which thebrackets of the frame F rest, and by which it is supported.

The rollers a and b are fluted and made of iron. I) revolves with thegear 0, and a, through the intermediate gear D and D, revolves with 0much faster than 0. Over those two fluted rollers b and a revolve theleathercovered rollers c and 6. These rollers are impelled by frictionfrom the Toners b and a, and

its right place between the rollers.

The roving is a thread of slightly-twisted cotton. It is held on thebobbin I, and after being drawn between the rollers a b and c e, asshown in Fig. 4, it is twisted into a perfectly-completed thread by whatis called a ring-twist.

So far we have described a common ringspinning frame. We now proceed todescribe our improved attachment.

Resting on and supported by the projections 1 l, which extend from theframeB, is, as shown in Figs. 1 and 4, the frame F, which supports thescavenger-rollers d and d. This frame F consists of the block m, towhich are attached the brackets G and G. These brackets are grooved ontheir inner sides through their whole length vertically, except at theirlower end, where the groove is closed, so as to retain the roller whenthe frame F is lifted from its connection with B. At the top and on oneside of the grooves, on one of the two brackets, are openings, by whichthe roller is removed from the frame.

These rollers d and d are shown by Fig. 3, and are made of wood or iron,and are covered with woolen cloth, the better to lick up the wastecotton. They have bearings extending from their ends, which rest in thegrooves i and z" of the brackets G G, and, for greater convenience, arecut away or nicked in the middle of the roller, dividing it into twoparts. These rollers are held above the rollers c and e by the groovedbrackets G G, and rest with all their weight upon them, being free tomove vertically in the groovesi and '5. This freedom permits the rollersto bear with equal pressure on 0 and 0, whether the rolls are bare orcovered with a thick accumulation of waste.

- Having described our invention, we now proceed to describe itsoperation. The end of the roving which is held on the bobbin I is passedthrough the two holes in the guide-bar K, and between the fluted ironrolls a and b and the leather covered rolls 0 and e, as shown in Fig. 4,the roving being stretched to much greater length by the greater speed.of the roller a than b. After passing between rollers a and 0, theroving is twisted by a device not shown in the drawings.

Now, having shown the working of the machine, it is obvious that if atany time it is found desirable to remove the scavenger-rollers, it canbe most conveniently and expeditiously done by lifting the frame, withthe rollers, from its supporting projections l and Z, and, when desired,can be quickly replaced.

What we claim, and desire to hold by Letters Patent, is

The detachable single frame F, having the standards G G, grooved at '5,closed at their bottoms, and provided with the openings h h,

in combination with the scavenger-rollers d FRANKLIN TWITGHELL.
